Employment
Experience
- Offer Builder Revamp
I single-handedly revamped an offer builder engine for a large telecommunication company in the United Arab Emirates. For this project, I worked on architecture design, development, and production support. Also, I implemented core new functionalities, including a store and save mechanism and parallel back-end API calls.
- ETL Enhancement
Optimized multiple Java-based ETL jobs to improve throughput and reduce memory footprint to increase job performance. The result was a performance increase, reducing the job execution time from 25 minutes to two minutes.
- Middleware Solution
A middleware solution for a financial institution that connected 12 different banking systems—both internal and external—to provide smooth communication and independent iteration to all systems. Developed a total of 89 REST APIs ranging from funds transfer and balance inquiry to mortgages. Performed SIT on the client side as well as the go-live activity and post-production support.
